Variety of basil plant named &#39;Green Ball&#39;

ABSTRACT

‘Green Ball’ is a new variety of non-flowering basil plant having a compact and rounded growth habit, high leaf production, and tolerance to low temperatures.

BOTANICAL CLASSIFICATION

Ocimum basilicum.

VARIETAL DENOMINATION

‘GREEN BALL’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of basil plant, botanically known as Ocimum basilicum and hereinafter referred to by the cultivar name ‘Green Ball’.

The new variety was discovered and selected by the breeder in a cultivated environment in July of 2009 in Wolsier, Germany (located in the region of Brandenburg) as a naturally occurring open-pollinated new variety in a population of unpatented and unnamed Ocimum basilicum plants. Subsequently, the new variety was asexually reproduced by cuttings in Wolsier, Germany in 2010. Further asexual reproductions at the same location has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained and reproduced true to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe 8-week-old plants grown in an open field with full sun, watered as needed, and receiving weekly fertilization treatments accented with nitrogen in Wolsier, Germany. The plants were exposed to daytime temperatures of 20-30° C., and evening temperatures of 10-20° C. Color observations were taken under natural light, and the color references are made to the R.H.S. Colour Chart of The Royal Horticulture Society of London, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variation in environment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to basic characteristics of ‘Green Ball’ which, in combination, distinguish this basil plant as a new and distinct cultivar:

1. Compact and rounded plant habit;

2. Sweet-spicy fragrance;

3. Aromatic taste;

4. Tolerant to Fusarium, Botrytis, and Pythium; and

5. Low temperature tolerance.

Further, the new variety exhibits a sweet-spicy fragance and aromatic taste like basil variety ‘Dark Lady’ (U.S. plant patent applied for concurrently). However, ‘Green Ball’ has green leaves and a compact and rounded growth habit, while ‘Dark Lady’ has very dark violet leaves and tall growth habit. The following Table 1 provides a further comparative listing of botanical characteristics of ‘Green Ball’ and ‘Dark Lady’.
